Finally got my 166 back on the road and absolutely love driving it, only problem is I'm getting no sound on the stereo. The tape deck is broken and rejects tapes and its saying no cd player fitted when I press the CD button even though the changer is in the boot. This doesn't bother me too much as I'm planning on fitting an AUX connection soon instead. However, when I go on the radio, it picks up the stations but there's no sound coming out of the speakers. On the very odd occasion I get a split second of sound but that's it. Its not on mute and the left volume knob seems to have no impact and everything else except the phone seems to work. Has anyone come across this before and is there an easy fix? I don't want to buy the stuff for the aux connection if I have no sound. I've looked at replacing the unit but its very expensive. I wouldn't mind if there was an upgraded ICS that has aux, latest maps for the nav etc. but I'm not sure anyone sells them so if anyone has a way of fixing this without replacing the unit it would be appreciated.
